Dan Snow explores the story of the Egyptian pharaoh's life and death, and the discovery of his tomb, assisted by journalist John Sergeant and archaeologist Raksha Dave. In the first episode, Dan visits the Egyptian Museum in Cairo to examine the mummies of the boy king's parents - who were brother and sister, an incestuous relationship that may have had a serious impact on their son's health. Raksha visits a new excavation in the Valley of the Kings, while John gets a taste of a pharaoh's diet.

Dan Snow journeys back to 1323 BC, as he investigates an injury the pharaoh sustained towards the end of his life, an injury that would eventually result in his death. A scan of Tutankhamun's skeleton reveals a break to his thigh bone, and whilst visiting the Grand Egyptian Museum, Dan comes across 130 walking sticks which were found in his tomb, which suggest the young king was unable to walk unaided before his death.

Dan Snow investigates why the faces on Tut's coffins and canopic jars look more like a woman, and archaeologist Raksha Dave examines a recently restored box used for the pharaoh's clothes and discovers evidence to suggest it may actually have belonged to Nefertiti. Meanwhile, John Sergeant revisits his Strictly days as he learns how to dance like an Egyptian at a funeral.
